Down a dirty alley in the Mission is an unexpectedly pleasant surprise: a vaulted warehouse where world-class DJs blast house, dubstep, and electronica until 4 am on weekends, with a Funktion One sound system and multiple bars to keep the hard-dancing, bohemian crowd happy. Meanwhile, the upstairs loft hosts more intimate live music, and the winding gallery shows works by artists in residence. Even better, they support non-profits: Part of the proceeds pay for art classes in local schools.
